My r4i 3ds card is not reading

Your R4i card has a microSD with FAT32 format and the respective kernel files inside? When you insert it on the 3DS, any icon is prompted on HOME Menu?

About the other question, take a look on this thread: https://gbatemp.net/threads/nds-forwarder-cias-for-your-home-menu.426174/

 

This happens to mean sometimes. What I do is take out the micro sd card and re-insert it.

 

Check the microSD card format and files. The respective kernel files must be on its root, if not, the flashcard wil be not recognized by any console

PS: Could you put here the exactly reference of your flashcard? (An image/photo of the flashcard, externally and internally, would be better)

can help change the format.

 

Is this the 3ds flashcard you have?

 

Wich one is your other card? Two days ago a R4 SDHC dual core (from around 2013) died while testing Twilight menu (not making asumptions that twlmenu killed it). I inserted and tested it in cartridge slot on a new 3ds xl, 3ds xl, nds lite and a nds fat, it is not recognized. Maybe some flashcarts are starting to die.

 

Sometimes the card isn't making good contact with the pins on the 3DS. Try putting tape on the back on the R4 (where the sticker is) to make it thicker so it'll push against the back into the card reader contacts. I had to do this on my M3i Zero to make contact with my DSi

 

Yeah same with mine. One day it just stopped working
